IMPROVEMENT IN HANGER-BOX FOR (iRANK-SHAFIS.

TO ALL WHOM IKT MAY OONCERN:

Be it known that I, THOMAS WELCH, of Chnrchville, in the `county ofMonroe, and State of New York, have invented a new and useful Hanger-Boxfor the Crank-Shaft and other Johrnais'of Harvesters; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof', reference beingl hadto the accompanying drawings, making partof this specification, in which- Figure 1 is a top view of my invention,thetop plate or cap of the case A being removed.

Figure 2 is a vertical section of the same, taken in the plane indicatedby the red line o, iig. 1.

Figure' is a transverse vertical section, taken in the plane indicatedby the ied line n, in gs. l, 2, and

Like letters indicate corresponding parts ih all the figures.

This invention consists, mainly, in providing the crank-shaft ofharvesters withself-adjusting, or self. lining boxes; and in providingthe said boxes and journals with an oil-chamber or reservoir, anda wickor stnfflng, whereby the oil is conveyed to the end of the journal,whence it is distributed over, the whole bearing.

To enable others to make and use my invention, I will describe itsconstruction and operation.

I provide the caseAv with a division plate or rest R, upon which theboxes B and B are supported. This plate extends from side to side of thecase, laterally, but an open space, C and D, is left at the ends. Thespace C is divided from the balance of \the chamber by bars a, figs. 2and 3, and constitutes a sort ofvpaclring cage for 4cotton waste orother suitable material. There is an opening lil-through the plate R,through which the end of the adjusting wedge E may pass. This wedge hasa cylindrical face next to the box `B, and ts in thecorresponding-shaped recess in the back of the box. The set-screw Siisdesigned to secure the proper adjustment of the Wedge against the box,by preventing it from working up the inclined plane and therebyloosening the' boxes. The box B is similarly fitted to a projecting ribF on the case A. The box B is made somewhat shorter than the other, asshown in iig. l, so as to permit the stuiing or waste to come in Contactwith the journal J.' There is an opening provided in the cap, I, overthe point G, (g. 1,) through which opening the' waste or stuihng isapplied. The cap, I, is made with an arch or elevation L, iig. 3, tomake room for the r wedge. The set-screw, S, is' tapped through'thisarch and acts against the top of the wedge, and b'y this means the partsmaybe tightened up. at any time to compensate for any Wear that mayoccur between the parts. The top and bottom of the boxes, B and B, aremade convex, longitudinally, as shown in g. 2.. They may be made ofchilled iron, and by means of the provisions made for their rocking.horizontally and vertically, they will line themselves to a perfect t tothe journal or shaft J without babbeting, and thereby accomplish1 theobject by a much simpler and cheaper method, and at the same timeprovide a much more substantial and durable box. The boxes may rest uponribs, top and bottom, similar to rib F if desired, or the ribs in eithercase may be upon the boxes and the case recessed. If ari-,iron frameisused for the machine, the case may be cast with the frame, and`the` cap,I, cast on or made separate and attached with bolts. If the-cap'is castto the ease, the wedge, Eshould be inserted and held with the upper endagainst the arch,` until the boxes and shaft J are inserted and properlyadjusted, when the wedge may drop to a bearing between the box B, andinclined plane K, and the set-screw S turned Adown against the top ofit. These boxes, B and B', may be taken from the sand andrattled, `orotherwise cleaned, and-adjusted inthe machinev as ab'ove described,without any other itting.- Brass or any other suitable materialv may beused for the boxes. vThe wedge may be dispensed with,

l by placing the set-screw S in the side of the case, so as to screwagainst the back of the box. A wedge or a i set-screw might 'be usedagainst the b c oth boxesit' desired. A set-*screw may be used on thetop of the boxes, by having an intervening late for the oint of thescrew to rest against.

What I claimas my inve tion, and desir to secure by Letters Patent, is-

l. Providing. the `ligger-journal of th crank-shaft, o r other journalsof harvesters, with self-adjusting or self-liningi/leaings or boxes,substantially asand for the purposes shown and described.

2.A The application of the wedge E, with or without a set-screw, whenused in combination with the box, in y which the journal revolves,forthe purpose of compensating for the slack that might otherwise occur bythe wearing away'of the parts. l

3. The setjscrew S, in combination with the self-adjusting orself-lining boxes of harvesters, substantiallyl as and for the purposeslset forth. A I

L5..v In combination with the self-lining or adjusting boxes andjournals, the oil reservoir, substantiallyas shown, and for the purposesdescribed. l

5. In combination with a set-screw and self-lining or self-adjustingboxes, in harvester's, the cap I, or its equivalent, for the purposesdescribed.
